Rivers and Streams
Bill
Nye Video Notes
* A river is moving water
* Water always flows downhill
* Rill = the
start of a river
* Rivers shape the land they flow through
* Rills flow together to make streams.
* Streams flow together to make rivers.
* Moving water stays going in the direction it is
going in
* Rivers constantly fill themselves in making them shallower
and shallower
* Meander = the curves or bends in a river
* Hydrologist = a
scientist who study's rivers and water in general
* Special ecosystem occur near rivers
* Waterfalls occur when different layers of hard and
soft rock exist in an area
* Humans build dams to prevent floods, create electricity,
and irrigate farmland
* When rivers churn, they oxygenate the water
* Continental
Divide = the highest point in the land (like the peak
of your roof) where water chooses its direction or path
